Reid Horuff c27061dae7 [rocksdb] 2PC double recovery bug fix ... Summary: 1. prepare() 2. crash 3. recover 4. commit() 5. crash 6. data is lost This is due to the transaction data still only residing in the WAL but because the logs were flushed on the first recovery the data is ignored on the second recovery. We must scan all logs found on recovery and only ignore redundant data at the time of replay. It is not possible to know which logs still contain relevant data at time of recovery. We cannot simply ignore a log because all of the non-2pc data it contains has already been written to L0. The changes made to MemTableInserter are to ensure that prepared sections are still recovered even if all of the non-2pc data in that log has already been flushed to L0. Test Plan: Provided test.
